Network Limits

When constructing a Passport network, make sure that the following limits are observed:

• Maximum number of netlinks per Passport 4400: 25.
• Maximum number of netlinks per physical port: 24.
• Maximum number of RFC 1490 PVCs per Passport 4400: 12.
• Maximum number of PANL DTEs per Passport 4400: 1.
• Maximum number of PANL DCEs per Passport 4400: 25.
• Maximum number of physical ports per Passport 4430/50/55: 19. The Passport 4430/50/55 contains three ports on the base module. With the addition of one or two High-speed Data Modules (HDM), it is possible to add up to 16 additional ports to the Passport 4400, for a total of 19 ports.
• Maximum number of physical ports per Passport 4460: 7. The Passport 4460 contains three ports on the base module with two on each SDM expansion module.
• Maximum number of Passport nodes in a Passport 4400 network: 25.
• Maximum number of levels in the Passport 4400 network hierarchy: 4. The Passport 4400 network nodes must be arranged in a hierarchy with no more than four levels of PANL communication. For example, the illustration shown below contains three network levels (consisting of units A, B-C, and D-G, respectively).
